If you are an early riser, plan to do things then or in the evening.
You can always go a pool in the afternoon or catch a movie, or just stay indoors.
I do not find the heat to be overbearing unless you are planning to exercise outdoors. The best thing is, "you don't have to shovel sunshine". The last winter was enough for me with Sandy and three feet of snow.
I would have a bottle of water with me, to prevent dehydration.
